UNITED STATES PATENT AUGUSTUS G. BURTON, OF CHICAGO, ILLINOIS, ASSIGNOR OF ONE-HALF TO DESTAING S. COVERT, OF SAME PLAGE. A

BURGLAR-PROOF SAFE.

SPECIFICATION forming part of Letters Patent No. 425,404, dated April 15, 1890.

Application filed December 6, 1889. Serial No. 332,783. (No model.)

To all whom it may concern:

Be it known that I, AUGUSTUS G. BURTON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Burglar-Proof Safes 5 and I do declare the following to be a full, clear, and ex-r act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to burglar-proof safes. Its purpose is to provide means for securing the hinges and the pressurebar, when one is used, to the safe and door in such manner that the plates will not be punctured by screw or bolt holes, whereby convenient lodginent for explosives is provided. Its further purpose is to provide for the easy adjustment of a close-litting door.

Figure l in the accompanying drawings shows the front elevation of a safe having my improvements. Portions of the hinges are shown in section. Fig. 2 shows a detail of the side elevation of the safe with the boss of the hinge partly removed. Fig. 3 shows a perspective of a portion of the safe with the hinge removed. Fig. i is a plan view of one of the hinges. Fig. is a rear elevation of a section of the hinge. Fig. 6 is an end elevation of the saine. Fig. 7 is an end elevation of the hingebracket on the safe-door. Fig. Sis a section view through l l, Fig. I. Figs. 9 and 10 are details of the adjusting device. Figs. l1, l2, and 1S show the construction of the hinge when the fixed brackets are set as far apart as the height of the door, both doorbrackets being between the leaves. One of the principal features of my invention consists in dovetailing the various external parts into the outer plate of the safe, the dovetailing recesses cutting but partially through the outer plate of the safe.

I show in the drawings a safe A, of ordinary form. Its door B is carried by the cranehinges C C, and the ordinary pressure-bar D is used to complete the operation of closing it. This pressure-bar consists of the shaft d, carried across the door in the journals E E and having the ecccntrics d d at its ends. These eccentrics engage in the hooks F F, which are fixed tothe face of the safe. The shaft CZ is rotated by the handle c, which is attached thereto, and by this means the door is closed by the action of the eccentrics. The hinges consist of the swinging leaves C C, united by the cross-bar c and pivotally secured to the door B by the brackets G and II and pins I and K and to the safe by the brackets G and II and pins I and K. The sections of the hinge-brackets may be cast entire or a separate block may be used to attach to the door or safe, the bracket being screwed to this block. The latter forni of construction is not shown, but is obvious.

' A shallow dovetailing channel a; (shown on an enlarged scale in Fig. 8) is cut in` the outer plate of the safe, preferably from an adjacent angle, to receive each of the fixed attachments E, F, Gr, G', H, and II', these parts being fitted thereto and held in place, if desired, by beating or setting the metal down upon them, as shown at y y. The base of the xed attachment may be of sufficient length to iill the channel oc completely, or a follower, as g g, may be used.

In order that the brackets G and II at the angle of the safe may sustain the strain in various directions incident to the swinging of the door, they are preferably made in sections h and h', the former being secured in the front and the latter in the side of the safe. The bracket may, however, be made in a single piece, dovetailed into one face only of the safe and secured by beating or setting the metal of the safe downupon it in the saine manner as indicated at y y.

As the object of my invention will be defeated unless the door may be iitted so closely in its casing as to leave no crevice for the introduction of explosives, and as the use of such a close-nttin g door is iinpracticable without an adjusting device,I provide for the ad j ustinent in the following manner: The hingepins I and K are made vertically adjustable by being secured either in the bracket or leaf of the hinge by a scrcw-threadl and being' provided with a shoulder l', which is adapted to serve as the bearingplate between the two parts of the hinge, so that by means of the screw-thread Z the parts of the hinge may be separated, thereby raising the door. 7When the bracket G is placed below the leaf C, as shown in Fig. 11,v space must be left between these two parts to allow for vertical adjustment. The pin is preferably adjusted to the bracket by the screw-thread l, the adjustable journal-box N heilig in the leaf. The weight of the door is carried by the bolt-head Z2 carrying the washer q.

T he pins I K are journaled in an adj ustable box consisting of the slot N and the sliding bearings n n, fitting therein and adapted to embrace the pin I, but not of suflicient size to fill the slot N. The bearings n fn, are held between the set-screws O O, which may be two or more in number for each hinge. By the use of the set-screws O the position of the door may be readily adjusted horizontally.

I claim- 1. As a new article of manufacture, a burglar-proof safe having the brackets of its hinges and pressure-bar dovetailed into the surface-plate of its body and door, substantially as described, and for the purpose set forth.

described, and for the purposes set forth.

4. In combination with a burglar-proof safe,

a door-adjusting device consisting of a vertically-adjustable hinge *pin and a laterallysliding hinge journal-box controlled by the Set-screws O, substantially as described, and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

AUGUSTUS G. BURTON.
